PIN REMOVING TOOL Filed April 5, 1932 Patented Feb. 21, 1933 UNITED STATES CLARENCE HILLIARD, OF PORT HENRY, NEW YORK PIN REMOVING TOOL Application filed April 5,

This invention relates to tools and more particularly to a tool adapted to facilitate the removal of pins in drive shafts or the like, which are provided with a ball at one end as a part of a universal joint or the like.

An object of this invention is to provide a tool in the form of a fixed clamping means which is so constructed as to securely hold the end of a ball shaft therein so as to facilitate the driving out of the pin disposed transversely of the shaft and within the ball portion thereof.

The above and various other objects and advantages of this invention will in part be described in and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing, wherein 220 Figure 1 is a detail perspective view of a tool constructed according to the preferred embodiment of this invention.

Figure 2 is an enlarged longitudinal section taken substantially through the center of this device.

Figure 3 is a view similar to Figure 2 but showing the end of a shaft mounted therein, the shaft having a pin to be removed through the use of this tool or holder.

Referring to the drawing wherein like numerals of reference designate corresponding parts throughout the several views, the numeral 10 designates generally a block of metal or the like which is provided with a socket or recess 11 opening through one face thereof, this socket being round in transverse section so as to receive the ball portion of a shaft having a ball or round head mounted thereon.

49 The block 10 is also provided with diametrically opposed recesses 12 and 13 which communicate at the inner end thereof with the socket 11 and open through the upper face of the block 10. The recess 12 also opens through one end of the block. This 1932. Serial No. 603,349.

socket 11 is disposed to one side of the center of the block 10 and the recesses 12 and 13 are of a length substantially equal one to another but terminate at the inner end thereof outwardly of the inner end of the socket 11.

A shaft S which has a ball or head 14 mounted on one end thereof, and which is provided with a transversely disposed pin 15, is adapted to removably seat in the socket or enlarged recess 11 and the pin 15 is adapted to rest on the inner end of the recesses 12 and 13 with the inner end of the head portion 14 disposed outwardly of the inner end of the socket 11.

The block 10 is also provided with an opening 16 which is disposed in alinement with the inner end of the recesses 12 and 13, and when the pin 15 is driven by means of a o driving pin or other tool, (not shown) the pin is adapted to be loosely disposed in this recess 16.

Preferably, the pin removing tool may be reverted and inserted in the passage 16, which passage will hold the pin removing tool in alinement with the confronting end of the pin 15 so that the pin can be driven out of the head 14 in the reverse manner from that heretofore described. Where the removing tool is inserted in the passage 16, this passage constitutes a guide passage for the removing tool so that the removing tool will be at all times maintained in direct alinement with the longitudinal axis of the e, pin 15.

t is readily apparent that, if desired, the removing tool is extended into the slot 12 for engagement with the adjacent end of the pin 15, and the pin 15 is driven through the ball 14 and into the pin receiving opening or passage 16. The socket 11 is of a size to loosely receive the ball 14b and through the use of the alined recesses 12 and 18, the shaft S is held against turning movement so that the pin 15 can be readily driven out. of the ball or head 14. If desired, this block 10 may be inserted in a vise or other clamping means so that the block 10 will be securely held a ainst movement.

In t e use of this device, the shaft S is inserted into the block 10 with the head 14 disposed in the socket 11 and the ends of the pin 15 projecting from diametrically opposed sides of the ball or head 14 disposed in the alined recesses 12 and 13. The desired tool may then be engaged with the end of the pin 15 within the socket 12, and this tool then hammered or other pressure may be applied to the removing tool so as to force the pin 15 outwardly of the ball 14 and into the pin receiving passage 16.

It is, of course, understood that various changes and modifications may be made in the details of construction and desi of the above specifically described embodlment of this invention without departin from the spirit thereof, such changes an modificatlons being restricted only by the scope of the followin claims.

What is c aimed is 1. A tool as set forth comprising a block having an enlarged socket opening through one face thereof, said block also having opposed recesses on each side of the socket and opening through said one face of the block, one of said recesses also having an opening through one end of the block, said block also having a passage therein communicating with the other of the recesses adjacent the inner end thereof and opening through the opposite end of the block.

2. A tool as set forth comprising a block having an enlarged socket opening through one face thereof, said block having diametrically opposed recesses extending laterally of the socket and communicatin at one end therewith, said recesses opening arough said one face of the block and one of the reoesses also opening through an end of the block, said block also having a passa e therein communicating at one end with t e other of the recesses and opening through the epposite face of the block.

3. A tool as set forth comprising a block having an enlarged socket therein opening through one face thereof, said block also having a pair of recesses extending laterally of the sides of the recesses and opening through said one face of the block, said recesses terminating at the inner end thereof outwardly of the inner end of the socket, one of said recesses opening through a face of the block adjacent said one face and said block having a passage therein communicating with the other of the recesses and opening-through another face of the block adjacent said one face.

4. A tool comprising a block having a passage therethrough open to the atmosphere at opposite ends of the block and also signature.
